Description: The Fast Fourier Transform (FFT) allows users to view the spectrum content of an audio signal. The FFT code presented here was written by Don Cross though his homepage appears to have subsequently been taken down. Rather than explain the mathematical theory of the FFT, I will attempt to explain its usefulness as it relates to audio signals-The Fast Fourier Transform (FFT) allows us ers spectrum to view the content of an audio sign al. The FFT code presented here was written by Do n Cross though his homepage appears to have subs equently been taken down. Rather than explain t he mathematical theory of the FFT.

Description: FFT and IFFT for 16-bits wave, you can
use this instead of convolution calculate, input samples must be 2^n.
If its not 2^n samples just stuff zero
in last array.
I already make it to C++ class you can
new a calss and do it easy,FFT and IFFT for 16-bits wave, you can use this instead of convolution calculate, input samples must be 2 ^ n.If its not 2 ^ n samples just stuff zeroin last array.I already make it to C++ Class you cannew a calss and do it easy

Description: 进行FFT变换。任何连续测量的时序或信号，都可以表示为不同频率的正弦波信号的无限叠加。而根据该原理创立的傅立叶变换算法利用直接测量到的原始信号，以累加方式来计算该信号中不同正弦波信号的频率、振幅和相位。当然这是从数学的角度去看傅立叶变换。(Any continuous time sequence or signal can be expressed as an infinite superposition of sinusoidal signals of different frequencies. The Fu Liye transform algorithm based on the principle is used to calculate the frequency, amplitude and phase of different sine wave signals by accumulating the original signals directly. Of course, this is the Fu Liye transformation from a mathematical point of view.)
